Definitions

Field	Contents	SI Unit Example
`PID`	Unique cohesive element property identification number. No default (Integer > 0)
`MID`	Normal and shear behaviors of the cohesive elements entry identification number. `MID` on PCOHE should refer to MCOHE or MCOHED entries. No default (Integer > 0)
`INT`	Integration scheme of the cohesive elements. Blank or 0 (Default) Gaussian integration scheme. 1 Closed form Newton-Cotes scheme. (Integer)
`THICKNESS`	Initial thickness of cohesive layer (applicable to MCOHED entry only). Real > 0 A positive real value implies the initial thickness is prescribed as a real value. AUTO Initial thickness is calculated from geometry. Default = 1.0
`SECANT`	Stiffness type. 0 (Default) Secant stiffness. 1 Tangential stiffness. (Integer)
`CORDM`	Material coordinate system identification number. 2 Blank (Default) Element local coordinate system. 0 Basic coordinate system. (Integer ≥ 0)

Comments

All cohesive element property entries should have unique identification numbers.
The cohesive material coordinate system is defined as the element local coordinate system by default or a prescribed system (CORDM = Integer ≥ 0). The material local 3-direction is taken as the cohesive normal direction corresponding to Mode I fracture, and the material local 1- and 2-directions correspond to Mode II and III fracture.
